I have an issue with Endpoint Server R77.30.03; this server has been updated in July from R77.30.01; and everything has worked fine until last day, when all the client went in disconnected state; after several hours of checks and restart (cpstop/cpstart and also reboot of the server) clients began to connect correctly to server (connected policy loaded); but today the issue happened again; I've notice within the logs these entries:
==> /opt/CPuepm-R77/logs/mod_jk.log <==
[Fri Oct 26 22:43:37.837 2018] [14420:4156471040] [error] ajp_get_reply::jk_ajp_common.c (2118): (all) Tomcat is down or refused connection. No response has been sent to the client (yet)
[Fri Oct 26 22:43:37.837 2018] [14420:4156471040] [error] ajp_service::jk_ajp_common.c (2600): (all) sending request to tomcat failed (unrecoverable), (attempt=1)
These messages appear when working with SmartEndpoint; and every task I try to perform on SmartEndpoint fail with timeout error (Communication Timeout Error - A timeout error occurred during communication to the server).
I supposed that there's some issue with Tomcat that cause the error with SmartEndpoint and cause the disconnection of the clients.
What can I check?
I've noticed also that there are two different instances of PostgreSQL (postgresql and postgresql9.2) each instance listen on a different port, and netstat reports connection only for the PostgreSQL 9.2; just I've never noticed this before, is it a normal behaviour?
Please help ... Thanks everybody
